STALL.

To all-whomit mag concern: I Be it known that I,"WAYLAND L. Roor, a citizen of the; United States, residing at Spokane, in the county of Spokane and State ofWashington, have invented a new and useful Stall, of which the following is a specification.

This invention relates to stalls, particularly to cow stalls for dairy farms, and has for its object to provide an improved attachment for the stall which will effectively cause the,cow to step backward during evacnation, the present device being particularly an improvement over the device shown in my former Patent No. 1,004,202, issued Septeinber 26, 1911. v

The present invention also aims to provide a device of the character indicated which shall be simple, substantial, compact and inexpensive in construction, as well as convenient and eflicient. in use.

. VVith' the foregoing general objects in view, the present invention resides essentially in a swinging member attached to the contact atits free end with the back of the cow when the cow humps her back, so that the cow will be forced to step backwardly, means being rovided for adjustably locking the said mem er at various positions.

Thepresent invention also resides in the novel construction, combination and arrangement of parts hereinafter more fully set forth and as'particularly pointed out in that t 's invention is susceptible of altera- -tions or deviations in its details'within the scope of the appended claims without departing from the spirit of the present invention.

The invention has been illustrated in its preferred embodiment, in the accompanying drawings, wherein like reference characters have been employedto denote corresponding parts, and wherein-- Figure l'is a perspective view of a stall embodying the attachment, as in use. Fig. 2 is 'a fragmental perspective of the attach-- ment. Fig. 3 is a sectional view of thestall;

embodying the attachment.

Referring specifically to the drawings, the stall floor whlch has been designated by the numeral 4, is provided at its rear end with l r the usual gutter 5 and at its forivard end with the stanchion frame 6 embodying the Speciflcati on of Letters Patent. Application filed September 12, 1012. Serial No. 720,074.;-

stanchion frame of the stall and adapted to the a pended claims, it being understood Patented May 20, 1913.

'upper horizontal member 6 and an upright 6". The stanchion 7 is mounted in the frame 6 as usual, forthe reception. of the head of the cow, the stanchion fitting around the neck of the cow to permit the cow to move its head upwardly and downwardly, but constraining the cow from leaving the stall. The foregoing parts are common in stall; constructions and maybe of any. desired type, the same not being of any moment.

In carrying out thepresent invention,-'a U-shaped yoke 8 is pivoted at its ends to the upper member 6 of the stanchion frame 6, the said yoke being bent from a strip or bar of fiat metal, and the intermediate portion being designated by, the numeral 9. The

ends of the yoke are pivoted to the frame 6 by means of a pair of upstanding projections 10 secured to the upper portion 6 of the frame and to which the arms of the yoke are pivoted by means of bolts, rivets or the like.

To the intermediate portion 9 of the yoke is secured a back piece 11 which is designed to contact with the back of the cow, the said piece 11 being preferably constructed from a bar of wood having its back secured to the intermediate portion 9 of theyoke by means of staples 12, the intermediate portion of bottom of the back piece being concaved or cut away as designated by the numeral 11* in order to receive the back of the cow and totend to prevent the cow from standing. other than at'right angles with the'frame 6. The piece 11 maybe suitably rounded or curved to comfortably fit the back ,of the cow and prevent chafing 'or other injur The said back piece 11 also serves to weight the free end of the yoke in order that the free end will swing downwardly when the .yoke is, I

free.

j The yoke 8 is permitted to be swung to various adjustments, and is normally designed to be locked againstswinging movements by the means describeddirectly. I A

. brace 13 is pivoted to the upright 6 of the stanchion frame, and a slide 14 is mounted on the corresponding arm of the yoke 8, this slide having a projection 14 extending along the corresponding arm of the yoke toward its fulcrum or pivotal point, to which pro ection the brace 13 is connected. The

arm of the yoke upon which the slide 14 is engaged is provided with a series of aper tures 15 through which a stop or bolt 16 is designed to be engaged for limiting the date the particular cow standing in the stall,

so thatthe yoke will not be permitted to swing upward or downward in order to dis turb or injure the cow, the slide bindin on the arin of the yoke when the yoke ten s to swing. It is preferable to have the back piece 11 normally spaced slightly above the back of the animal, or out of contact with.

the animals back in order to permit a free and uninterrupted slight movement of the cow while eating.

' on the arm of and will effectively accomplish the object The yoke is locked against downward or upward movement, for the reason that when the yoke tends to swing, the projection 14* of the slide will'be swung relative to the yoke by the brace 13, so that the slide 14 willf. bmd or grip on the corresponding arm of the.

yoke and prevent the yoke from swinging. It will therefore follow that the brace bein pivoted eccentrically to the slide 14 will loci the yoke at any position,

aimed at.

This attachment is simple and compact, and may be readily applied to present day stalls without 'materia alterations, and this device will be seen to be advantageous for the purpose for which it is designed.

By swinging the brace 13 u ward, the slide 14 may" be made to trave inwardly upon the corresponding arm of the yoke so as to swing the yoke u wardly, in' which event, the slide will bin u on the arm of the yoke so as to lock the yo e in raised position. The yoke may thus be raised and locked out 0 normal position so as' to be out of the way of the animal or the attendant, and the oke may be readily positioned for use b re easing the slide from the arm of the yo e so that the yoke is permitted to swing downwardly to the proper osition, in which event, the slide may again ock the yoke against swinging movement.

Having thus described the invention, what is claimed as new is 4 1. In a stall, a stanchion frame, a member pivoted to the frame and designed to contact with an animals back, a binding member slidable on thesaid member, and a brace pivoted to the frame and pivoted eccentrically to the said binding member to bind same on the first mentioned member when the latter is given a swinging tendency.

2. In a stall, a stanchion frame, a U- shaped yoke pivoted at its ends to the frame, the intermediate portion bein desi ed to contact with an animals bac a member slidable on one arm of the yoke, and a brace pivoted tothe frame and pivoted eccentrically to the said binding member in order to cause the same to bin on the said arm when the yoke is given a swinging tendency.

3. In a stall, a stanchion frame a yoke pivoted to the frame, and designed to contact with an animals back, a binding member slidable on the yoke and having a projection and a brace pivoted to the said frame and connected to the said projection.

-1. In a stall, a stanchion' frame, a U- shaped yoke pivoted at its ends to the frame,

'"the intermediate portion being designer} to in m contact with an animals back, a member slidable on one arm of the yoke an having a (projection extending along said armtowar mding the fulcrum thereof, and a brace pivoted to the frame and connected to the said projection.

5. In a stall, a stanchion frame, a U- shaped yoke pivoted at its ends to the yoke, the intermediate portion of the yoke being designed to contact with an animals back a binding member slidable on one arm of e yoke and having a projection extending toward the fulcrum of the yoke, an adjustable stop on the said arm for limiting the downward movement of the bindinigrmember and a. brace pivoted to the said time and adjustably connected to the said projection of the binding member.

In testimony that I claim my own, I' have hereto aiiixed my in the presence of two witnesses.
